NAME
    Perinci::Sub::ValidateArgs - Validate function arguments using schemas
    in Rinci function metadata

VERSION
    This document describes version 0.011 of Perinci::Sub::ValidateArgs
    (from Perl distribution Perinci-Sub-ValidateArgs), released on
    2019-04-15.

SYNOPSIS
     use Perinci::Sub::ValidateArgs qw(gen_args_validator);

     our %SPEC;
     $SPEC{foo} = {
         v => 1.1,
         args => {
             a1 => {
                schema => 'int*',
                req => 1,
             },
             a2 => {
                 schema => [array => of=>'int*'],
                 default => 'peach',
             },
         },
         'x.func.validate_args' => 1,
     };
     sub foo {
         state $validator = gen_args_validator();
         my %args = @_;
         if (my $err = $validator->(\%args)) { return $err }

         ...
     }

    or, if you want the validator to die on failure:

     ...
     sub foo {
         state $validator = gen_args_validator(die => 1);
         my %args = @_;
         $validator->(\%args);

         ...
     }

DESCRIPTION
    This module (PSV for short) can be used to validate function arguments
    using schema information in Rinci function metadata.

    There are other ways if you want to validate function arguments using
    Sah schemas. See Data::Sah::Manual::ParamsValidating.

FUNCTIONS
  gen_args_validator
    Usage:

     gen_args_validator(%args) -> any

    Generate argument validator from Rinci function metadata.

    This function is not exported by default, but exportable.

    Arguments ('*' denotes required arguments):

    *   die => *bool*

        Whether validator should die or just return an error
        message/response.

    *   meta => *hash*

        If not specified, will be searched from caller's %SPEC package
        variable.

    *   source => *bool*

        Whether we want to get the source code instead.

        The default is to generate Perl validator code, compile it with
        "eval()", and return the resulting coderef. When this option is set
        to true, the generated source string will be returned instead.

    Return value: (any)
